How often should you oil a rosewood fretboard?

A short answer: every time you change your strings. With the strings off and the fingerboard bare, it’s the ideal opportunity to clean the board and give the timber a light conditioning with fretboard oil.

How often that happens will naturally vary from player to player. A regularly played guitar may see fresh strings every few weeks or months, while another instrument might go considerably longer between changes. Either way, making fretboard care part of your string-change routine keeps things simple: strings off, board cleaned, lightly conditioned, then restrung.

Climate and storage conditions matter too. A guitar kept in a dry, heated or air-conditioned room can lose moisture faster than one kept in a stable, temperate environment. Watch the wood as well as your routine. If the grain begins to look pale, grey or dry, the fingerboard may be ready for some attention.

When you do oil the board, a little goes a long way. Apply a small amount and work it evenly into the timber with a clean cloth. Allow it a few minutes to condition the wood, then thoroughly buff away anything remaining on the surface. The aim is to leave the fingerboard conditioned and clean — never wet or greasy.

Make it part of the ritual: old strings off, fingerboard cleaned and conditioned, fresh strings on. It only takes a few minutes, and regular light maintenance helps keep a rosewood fretboard looking and feeling its best for years to come.
